Merge tag 'dm-4.7-changes' of git://git./linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

 - based on Jens' 'for-4.7/core' to have DM thinp's discard support use
   bio_inc_remaining() and the block core's new async __blkdev_issue_discard()
   interface

 - make DM multipath's fast code-paths lockless, using lockless_deference,
   to significantly improve large NUMA performance when using blk-mq.
   The m->lock spinlock contention was a serious bottleneck.

 - a few other small code cleanups and Documentation fixes

* tag 'dm-4.7-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
  dm thin: unroll issue_discard() to create longer discard bio chains
  dm thin: use __blkdev_issue_discard for async discard support
  dm thin: remove __bio_inc_remaining() and switch to using bio_inc_remaining()
  dm raid: make sure no feature flags are set in metadata
  dm ioctl: drop use of __GFP_REPEAT in copy_params()'s __vmalloc() call
  dm stats: fix spelling mistake in Documentation
  dm cache: update cache-policies.txt now that mq is an alias for smq
  dm mpath: eliminate use of spinlock in IO fast-paths
  dm mpath: move trigger_event member to the end of 'struct multipath'
  dm mpath: use atomic_t for counting members of 'struct multipath'
  dm mpath: switch to using bitops for state flags
  dm thin: Remove return statement from void function
  dm: remove unused mapped_device argument from free_tio()
